Explanation:
As, this question is incomplete and without data we can not answer this question. But we can make it complete by adding our own values. Let's do it and calculate.
Let's suppose, there are 10 students in the class of Mrs. Brim and she took 5 tests on subsequent days and made chart to know the average time her students took to solve the test.
Total time of test = 30 minutes
Average time taken by the students to solve the test on Day 1 = 25 minutes.
Average time taken by the students to solve the test on Day 2 = 27 minutes.
Average time taken by the students to solve the test on Day 3 = 22 minutes.
Average time taken by the students to solve the test on Day 4 = 23 minutes.
Average time taken by the students to solve the test on Day 5 = 20 minutes.
Average Time in all Tests = Sum of all times / total number of days
Average Time = (25 + 27 + 22 + 23 + 20) / 5 days
Average Time = 117/5
Average Time = 23.4 minutes is the time that Mrs Brim wanted to see.
